He's a real solid buck. I"d probably try to shoot him as he slipped through that opening and shoot over his back, then skip off a rock on the ground, then bounce the bullet into the brisket of that buck behind him.
Left G2 is long. Nice typical 4 point but not a giant. My first impression is that he is a 4 1/2 year old buck that has potential but that is just pure speculation on my part. If I saw him on my NM hunt this year and only had a few seconds to decide, I would be pulling the trigger.
They always fool you and look bigger with their ears laid back. He is a younger deer (not much bigger body than the third buck, small same sized head, narrow chest). I'm only putting him in the upper 160's to low 170's.
